  • The United States is one of three OECD countries that does not provide universal access to paid sick leave for all employees. Over the past years, just 12 states have passed sick pay mandates. In a new working paper, P4A researcher Nicolas R. Ziebarth of Cornell University and colleagues Catherine Maclean and Stefan Pichler provide first-of-its-kind evidence on how state-level sick pay mandates affect coverage rates, sick leave utilization, and labor costs.

  • The U.S. is one of three industrialized countries without universal access to paid sick leave. Thirty-five percent of all full-time employees lack this coverage. Among low-income and part-time employees, uninsurance rates exceed 80 percent. In addition to concerns about inequality, worker well-being, and productivity, a lack of paid sick leave also contributes to the spread of disease, when ill workers are forced to choose between their health and their job.
